Description

[Technical field]

[0001] The present invention relates to a security equipment capable of wirelessly supplying power from a power source located inside a building to a surveillance camera unit installed outside a building via a contactless power supply device including a contactless power receiving component and a contactless power transmitting component, and a security system including the security equipment. [Background technology]

[0002] Surveillance cameras have traditionally been used as a crime prevention measure in homes, stores, offices, etc., and surveillance camera devices are known that not only capture images but also have a variety of functions, such as converting the optical signal of the image into an electrical signal and storing the converted electrical signal. Surveillance cameras, also known as security cameras, are installed for purposes such as preventing accidents and crimes. However, if an accident or crime occurs, it is also possible to use the images or video data from surveillance cameras in the surrounding area to help investigate the cause of the accident or crime.

[0003] The following Patent Documents 1 and 2 disclose security cameras with improved image quality, storage devices for storing video information, and security cameras with a function capable of transmitting image information to a specific terminal via the Internet. The following Patent Documents 3 and 4 disclose a non-contact power supply technology that uses electromagnetic induction technology to supply power to devices without contacts for charging smartphones. The following Patent Document 5 discloses a surveillance camera system that obtains the main power supply to the surveillance camera from the current of a distribution line using an electromagnetic induction method, since a power source of about 220V is normally required for a surveillance system on a general road, a walking path, etc., but it is difficult to secure such a high-voltage power source externally and installation work is expensive. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Special Publication No. 8-31196 [Patent Document 2] Patent No. 5183536 [Patent Document 3] Patent No. 4057038 [Patent Document 4] Patent No. 5160858 [Patent Document 5] Special Publication No. 2016-517261 Summary of the Invention [Problem to be solved by the invention]

[0005] The above Patent Documents 1 and 2 disclose security cameras that can obtain high image quality, and surveillance cameras that can record on digital media and transmit to a specific terminal via the Internet, and these surveillance cameras are usually installed outdoors. However, to install security cameras outdoors, wiring work is required to supply power from inside to outside in addition to the installation work of the camera, which is time-consuming and costly. In addition, there are cases where the owners of these buildings, such as condominiums and apartments, decide not to perform wiring work. Furthermore, there are cases where it is difficult to open through holes in walls, etc. for wiring work in buildings with airtight walls and windows.

[0006] The above Patent Documents 3 and 4 disclose a contactless power supply technology that uses electromagnetic induction technology to supply power to devices without contact for charging a smartphone, but make no disclosure about transmitting power to a surveillance camera installed outdoors using an indoor power source. The surveillance camera system disclosed in Patent Document 5 listed below etc. obtains the main power source to be supplied to the surveillance camera from the current of a power distribution line installed outdoors using an electromagnetic induction method, but there is no description regarding the use of an indoor power source to supply power to a surveillance camera etc. installed outdoors from indoors.

[0007] Furthermore, in security devices that use batteries for power supply, battery replacement is time-consuming, and there is a risk that forgetting to replace the batteries will cause the surveillance camera unit itself to stop operating. On the other hand, security devices that use solar cells for power supply are also known, but they require rechargeable batteries for stable nighttime operation of cameras, etc., which can lead to high equipment costs. Furthermore, if batteries are used and all security devices are installed outdoors, there is a risk that the entire security equipment will be stolen. [Means for solving the problem]

[0008] In view of the above-mentioned conventional technology, the inventors have discovered that by using a contactless power supply device including a contactless power transmitting component and a contactless power receiving component, it is possible to wirelessly supply power to a surveillance camera unit placed outdoors using a power source from indoors, without the need for electrical wiring work that penetrates the walls of a building from indoors to outdoors, and that by making the surveillance camera unit lighter, it is easier to install the surveillance camera unit, including the wiring work, thereby solving the above-mentioned problems, and have thus completed the present invention. That is, the gist of the present invention is the invention described in the following (1) to (6).

[0009] (1) A surveillance camera unit that is installed outdoors and has a function of converting captured images into electrical signals using an image sensor and then transmitting them to an external communication device; a non-contact power supply device including a non-contact power receiving part installed outdoors and supplying power to the surveillance camera unit, and a non-contact power transmitting part installed indoors and transmitting power to the non-contact power receiving part, This security equipment (hereinafter sometimes referred to as the first embodiment) is characterized in that the non-contact power transmitting component and the non-contact power receiving component are fixed in opposing positions via a wall portion or a glass portion of a glass window that separates the indoor and outdoor sides of a building, thereby making it possible to supply power to the surveillance camera unit from a power source on the indoor side via a non-contact power supply device. (2) The non-contact power transmitting component and the non-contact power receiving component are fixed by magnets in opposing positions to the glass of a window that separates the indoor and outdoor sides of a building, Furthermore, a surveillance camera unit is attached to the non-contact power receiving component. The security equipment described in (1) above.

[0010] (3) The surveillance camera unit is disposed at a position separate from the non-contact power supply device and is capable of receiving power from the non-contact power supply device via an electric wire cord. The security equipment described in (1) above. (4) The security equipment according to any one of (1) to (3), wherein the surveillance camera unit is equipped with one or more devices selected from (i) an optical sensor and an infrared LED, (ii) a human presence sensor, and (iii) a microphone for recording voice.

[0011] (5) The security equipment according to any one of (1) to (4), wherein the contactless power supply device comprises a contactless power transmitting component having a power transmitting coil and a contactless power receiving component having a power receiving coil, and power can be transmitted between the two components contactlessly by an electromagnetic induction method or a magnetic field resonance method. (6) The security equipment according to any one of (1) to (5) above; (i) An external communication device that receives, via the Internet, an electrical signal transmitted from the security equipment via a wireless communication network, and includes a computer having the function of monitoring and storing the received information; or (ii) an external communication device that receives the electrical signal transmitted from the security equipment via a wireless communication network via the Internet and that is a computer having a function of monitoring and storing the received information; A mobile terminal capable of communicating with the Internet via a mobile communication network, The present invention relates to a security system (hereinafter, sometimes referred to as a second embodiment). Effect of the Invention

[0012] According to the present invention, when security equipment such as a surveillance camera is installed on the outdoor side of a building, the non-contact power receiving component and the non-contact power transmitting component are fixed in positions opposite each other through the wall or glass part of a glass window that is installed to separate the outdoor and indoor sides of the building, and power is transmitted to the surveillance camera unit using a non-contact power supply device. This eliminates the need for wiring work that previously was required, such as passing through a wall of a building, and makes it easy to use power from inside the building. When a lightweight surveillance camera unit is attached to the contactless power receiving component of the contactless power supply device, security equipment can be easily installed on the glass portion of a glass window. In addition, the security equipment of the present invention makes it possible to minimize the amount of wiring cables around the surveillance camera unit housing, and in particular, when the surveillance camera unit is attached to a contactless power supply device, it is possible to almost completely eliminate the wiring cables outside the surveillance camera unit housing, making installation work and maintenance after installation easier.

[Diagram 3] 1 is an explanatory conceptual diagram of a security system showing an example of an embodiment of the present invention; [Figure 4] 1 is an explanatory block diagram of a security system showing an example of an embodiment of the present invention; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The present invention will be described below separately as a security facility (first embodiment) and a security system (second embodiment). (1) Security equipment (first embodiment) The security equipment of a first embodiment of the present invention is a security equipment including a surveillance camera unit that is installed outdoors and has the function of converting captured images into an electrical signal using an image sensor and then transmitting it to an external communication device, a non-contact power supply device having a non-contact power receiving component installed on the outdoor side and supplying power to the surveillance camera unit, and a non-contact power transmission component installed on the indoor side and transmitting power to the non-contact power receiving component, wherein the non-contact power transmission component and the non-contact power receiving component are fixed in opposing positions via a wall portion or a glass portion of a glass window that separates the indoor and outdoor sides of a building, thereby making it possible to supply power to the surveillance camera unit from a power source on the indoor side via the non-contact power supply device.

[0015] The security system of the present invention will now be described with reference to the drawings. 1 is a conceptual diagram of a cross section of a security system showing an example of an embodiment of the present invention, in which an outdoor-side non-contact power receiving part 21 and an indoor-side non-contact power transmitting part 24 are fixed to opposing positions on the glass surface of a glass window by outdoor-side magnets 22, 23 and indoor-side magnets 25, 26, respectively, with glass part 27 in between. A surveillance camera unit 2 is attached to the outdoor-side non-contact power receiving part 21, and a camera housing part 11 is housed in a housing 13, and the front of the camera housing part 11 is covered with a waterproof transparent cover 14.

[0016] 2 is a conceptual diagram of a front view of a surveillance camera unit 2 showing an example of an embodiment of the present invention, in which a photographing lens 12 is arranged in the center of a camera housing section 11 in a housing 13, and a plurality of infrared LEDs (Light Emitting Diodes) 16 are arranged concentrically around the lens 12, and an optical sensor 15 is arranged outside the infrared LEDs 16, and these components are covered with a waterproof transparent cover 14. Also, a human presence sensor 17 is arranged outside the waterproof transparent cover 14 to avoid the influence of infrared rays from the infrared LEDs 16. Below, the security equipment of the present invention will be further divided into a non-contact power supply device and a surveillance camera unit and described.

[0017] (1-1) Non-contact power supply device The use of non-contact power supply (wireless power supply) is spreading to mobile terminals such as smartphones, electric vehicles, and other industrial equipment. Known non-contact power supply methods include the electromagnetic induction method and magnetic resonance method, which belong to the "magnetic field coupling method" that use a magnetic field as a medium for power transmission, and the "electric field coupling method" that uses an electric field. In the present invention, any of the non-contact power supply methods can be used, but the "electromagnetic induction method" and "magnetic field resonance method", which belong to the magnetic field coupling method and transmit power by transmitting a high-frequency fluctuating magnetic field from a power transmission coil to a power receiving coil, are preferable from a practical perspective. In the above magnetic field coupling method, a non-contact power transmission component having a power transmission coil and a non-contact power receiving component having a power receiving coil are provided, and power is transmitted between the two components in a non-contact manner by the electromagnetic induction method or the magnetic field resonance method. Among the above magnetic field coupling methods, it is more preferable to use the electromagnetic induction method, which has a relatively high transmission efficiency and is suitable for small-power close-range power transmission. The non-contact power supply method will be specifically described below.

[0018] (i) Electromagnetic induction method The principle of electromagnetic induction power supply is that when two coils, a transmitting coil and a receiving coil, are placed opposite each other, when the current flowing through the transmitting coil changes, the generated magnetic flux changes, generating an electromotive force in the receiving coil, and an induced current flows. This method utilizes the "law of electromagnetic induction." This method is suitable for close-range power transmission of small power, and can be realized at low cost because the circuit configuration can be simplified and made compact, and is relatively efficient, but on the other hand, this method has a short transmission distance and is easily affected by misalignment between the transmitting coil and the receiving coil. For the electromagnetic induction method, the Wireless Power Consortium (WPC), an industry group on contactless power transfer technology, established the Qi standard in 2010, and it has become widespread for charging electric toothbrushes, electric shavers, smartphones, etc. Currently, the standard supports contactless power transfer up to a maximum of 15W, but studies are underway with a view to transferring power up to 120W in the future.

[0019] (ii) Magnetic resonance method In the above electromagnetic induction method, if the transmitting coil and the receiving coil are misaligned, part of the magnetic flux becomes leakage flux, and the transmission efficiency drops sharply. The magnetic resonance method was introduced as a method to improve the drop in transmission efficiency caused by this misalignment, and it is a method in which a capacitor is inserted into the coils on the transmitting and receiving sides to form an LC resonance circuit and strengthen the degree of magnetic coupling between the transmitting and receiving sides. The transmission distance in the magnetic resonance method is about 0.1 to 100 cm, the transmission power is about 0.1 to 1000 W, and the transmission efficiency is about 40 to 90%. Since it can be used when long-distance transmission is required, improvements to its efficiency are being considered for use in charging electric vehicles, etc. In addition, medium-capacity (1 kW) wireless power supply systems for industrial equipment have been put to practical use.

[0020] (iii) Capacitive coupling method The electric field coupling method uses a phenomenon in which a capacitor is formed with electrodes facing each other on the power transmitting and receiving sides, and when electricity is passed at a high frequency, electricity also flows through the opposing electrode (harmonic current). The transmission distance is as short as that of the electromagnetic induction method, but it is less susceptible to positional misalignment and generates less heat in the power transmitting section. The transmission distance in the electric field coupling method is about 1 to 10 cm, the transmission power is about 0.1 to 1000 W, and the transmission efficiency is about 80 to 90%.

[0021] FIG. 1 shows an example of an embodiment using the electromagnetic induction method, in which a non-contact power supply device 5 has a non-contact power transmitting component 24 arranged on the indoor side and a non-contact power receiving component 21 arranged on the outdoor side, and these are fixed in opposing positions by magnets 25 and 26, and 22 and 23, respectively, via the glass part 27 of a glass window that separates the indoor and outdoor sides of the building, making it possible to supply power to the surveillance camera unit 2 from a power source on the indoor side via the non-contact power supply device 5. In addition, the contactless power supply method can provide power supply even if there is an object made of a material that does not block magnetic fields, such as glass or non-metallic building materials, between the coil included in the contactless power transmission component and the coil included in the contactless power receiving component, so contactless power supply is possible even through the wall of a building that does not contain metallic materials that block magnetic fields. When the electromagnetic induction method is adopted, it is considered possible to supply power to the logical side if the thickness of the building wall and the glass part of the glass window are each about 1 cm or less, and when the magnetic field resonance method is adopted, the thickness of the wall and the glass part are each about 1 m or less. When the magnetic field resonance method is adopted, considering that the contactless power transmission component and the contactless power receiving component are fixed in positions opposite each other, it is preferable that the thickness of the thin wall is about 10 cm or less.

[0022] When the non-contact power transmitting component and the non-contact power receiving component are fixed to a wall separating the indoor and outdoor sides of a building or to the glass of a glass window, they can be attached to this by installing a mounting device, but when they are fixed to the glass surface of a glass window, it is also possible to fix them in opposing positions by attaching magnets to the non-contact power transmitting component and the non-contact power receiving component, respectively. With the spread and weight reduction of drive recorders, smartphones, etc., surveillance camera units have also become lighter, and the glass used for glass windows can be made of normal glass, thicker glass, tempered glass, impact-resistant transparent synthetic resin plates, etc., so it is possible to fix a surveillance camera unit to a non-contact power supply device that is fixed to the glass part of a glass window using a magnet in addition to the wall part of a building. Note that when using the above-mentioned electromagnetic induction method, if a magnet is used to fix the non-contact power transmission component and the non-contact power receiving component, there is a risk of affecting the magnetic flux in the non-contact power supply device, but since the range that affects the magnetic flux in electromagnetic induction power supply is limited to a few centimeters or less, it is possible to avoid the effect of the magnetic flux by adjusting the distance between the magnet and the coil of the non-contact power transmission component and the coil of the non-contact power receiving component.

[0023] (1-2) Surveillance camera unit The surveillance camera unit of the present invention is installed outdoors and has a function of converting captured images into electrical signals by an image sensor and then transmitting them to an external communication device. Along with the spread of drive recorders, smartphones, and the like, surveillance cameras are becoming more and more compact, lightweight, and energy-efficient. It is also possible to reduce the weight of surveillance camera units by further attaching one or more devices selected from the group consisting of optical sensors, human presence sensors, infrared LEDs, and audio recording microphones to the surveillance camera. An example of the arrangement of a surveillance camera unit and a contactless power supply device in the security system of the present invention is shown below.

[0024] As shown in Fig. 1, the non-contact power receiving part 21 and the non-contact power transmitting part 24 constituting the non-contact power supply device 5 are attached via the glass part 27 of a glass window separating the indoor side from the outdoor side of a building, and the lightweight surveillance camera unit 2 can be attached to the non-contact power receiving part 21. When the surveillance camera unit 2 is attached to the non-contact power receiving part 21 via a support 19, it is preferable that the support 19 has a function of allowing the angle of the camera lens surface to be adjusted in the horizontal and vertical directions. Also, taking into consideration the size and mass of the non-contact power supply device 5 and the surveillance camera unit 2, it is also possible to install them on the wall of a building using a mounting fixture instead of a glass window.

[0025] On the other hand, in addition to being attached to the non-contact power supply device 6, the surveillance camera unit 2 can also be installed at a location a short distance away from the non-contact power supply device 6, as shown in Figure 3 described below. In this case, the surveillance camera unit 3 receives power via an electric wire cord 42 from the non-contact power supply device 6 installed on the wall of a building or the glass part of a glass window. As described above, FIG. 2 shows a conceptual diagram of a front view of a surveillance camera unit, illustrating one example of an embodiment of the present invention.

[0026] For surveillance camera units, the following items need to be considered: image quality, nighttime photography, and waterproofing / splash-proofing of the photography lens. The standard image quality of images from security cameras is generally around 250,000 to 420,000 pixels. Regarding the nighttime shooting function, the minimum subject illuminance is the minimum illuminance (brightness) required for a surveillance camera to capture a subject, expressed in lux (lux). A surveillance camera needs an illuminance of about 0.5 lux to recognize a person's face. To obtain clear images regardless of day or night, the Day & Night function, which will be described later, can be used. The Day & Night function is a function that distinguishes the surrounding brightness using visible light and can capture clear images regardless of day or night. It captures visible light in color during the day, and switches to black and white shooting using near-infrared light, which is invisible to the human eye, at night, where noise is likely to occur, to capture clear images with less noise.

[0027] The waterproof and drip-proof functions of the photographic lens are particularly important since surveillance cameras are installed outdoors, and it is preferable to take measures such as installing a canopy-like cover over the top of the photographic lens or covering the front of the surveillance camera unit 2 with a waterproof transparent cover 16 as shown in Figure 1. The protection grade is determined by a symbol (IP code) beginning with IP and a two-digit number as a standardization of the waterproof and dustproof performance of electronic devices such as cameras and mobile terminals such as smartphones. The left side of the number is rated in five stages for "resistance against dust and dirt," and the right side is rated in eight stages for "resistance against water," with the higher number indicating higher performance.

[0028] The surveillance camera unit 2 is a device (element) that senses the captured optical image and converts it into a digital electrical signal using a CCD or CMOS image sensor, which also has the function of converting the image into a digital electrical signal using a transfer circuit method and wirelessly transmitting it to an external communication device. A CCD (Charge Coupled Device) is a semiconductor element that converts an image into an electrical signal and extracts it. It is about 1 cm in length and width and is made up of small pixels arranged in a grid pattern like a checkerboard. On the other hand, a CMOS (Complementary Metal Oxide Semiconductor) also has the same mechanism as a CCD, converting electric charges into an electrical signal using a photodiode and an amplifier, but a CMOS image sensor has a structure in which one photodiode is paired with one amplifier, making it less susceptible to noise during the transfer process.

[0029] Although it is possible to provide a storage device in the main body of the surveillance camera unit with the function of storing information captured by the surveillance camera, the optical image captured by the surveillance camera is converted into a digital electrical signal and then transmitted to an external communication device. In this case, if the surveillance camera unit is equipped with one or more devices selected from a light sensor, an infrared LED, a human presence sensor, a microphone for recording voice, etc., described below, in addition to the image data, it is possible to transmit information obtained from these devices as well. Examples of such communication functions include wireless LAN (Local Area Network) including WiFi (registered trademark), Bluetooth (registered trademark), BLE (Bluetooth Low Energy (registered trademark)), Zigbee (registered trademark), and the like.

[0030] The surveillance camera unit of the present invention is installed outdoors and has the function of converting captured images into electrical signals using an image sensor and then transmitting them to an external communication device, and can further be equipped with one or more devices selected from the following (a) to (c): (a) Light sensor and infrared LED By attaching a light sensor that detects light intensity and an infrared LED around the camera lens, infrared night vision functionality can be achieved, making it possible to take photos at night. (b) Human presence sensor By attaching a motion sensor around the camera lens, it becomes possible to control the surveillance camera so that the shooting switch is turned on to start shooting when the motion sensor detects a human figure. (c) Audio recording microphone By mounting a voice recording microphone for picking up the voices of people in the monitored area, the voice information collected by the microphone can be transmitted to an external communication device together with the electrical information of the image. The above devices (a) to (c) will be described in more detail below.

[0031] (i) Light sensor and infrared LED As shown in FIG. 2, when a light sensor 15 for detecting light intensity and an infrared LED 16 are arranged around the photographing lens 12 of the surveillance camera unit 2 of the present invention, nighttime photography becomes possible using the infrared night vision function. It is desirable that the surveillance camera unit has sensitivity in both the visible and infrared ranges so that images can be captured at night using infrared light as a light source. It is preferable that the optical sensor 15 is arranged around the lens 12 at a slight distance, and that the infrared LEDs 16 are arranged in a concentric circle around the lens 12 to make the whole unit compact. The optical sensor 15 detects the light intensity of the area to be monitored to determine whether it is day or night, so that it is possible to shoot in the visible light shooting mode (color shooting mode or day mode) during the day, and to switch to the infrared light shooting mode (black and white shooting mode or night mode) by turning on the infrared LEDs 16 at night when the light intensity detected by the optical sensor 15 is low. The function of shooting by distinguishing between day and night in this way is called the day and night function. The optical sensor 15 detects the light intensity and converts it into an electrical signal, and a semiconductor optical sensor such as a CDS sensor or a photodiode can be suitably used.

[0032] (ii) Human presence sensor A human presence sensor 17 can be attached to the front of the surveillance camera unit 2, for example on the outside of a waterproof transparent cover 14, as shown in FIG. 2. When the human presence sensor detects a human shadow, the surveillance camera can be activated and controlled to monitor activity. It is also possible to notify a computer 32 and a mobile terminal 34 as an alarm via a mobile communication network described later, as shown in FIG. 4. A human presence sensor is a sensor that detects infrared rays emitted by objects to be detected, and utilizes the fact that anything that has heat, including humans, emits infrared rays. When a person enters the monitoring area of ​​the human presence sensor 17 in a location where security equipment 1 is installed, the human presence sensor 17 detects the intruder, and the detection signal is sent to the control device, which turns on the CCD image sensor, etc. This causes the surveillance camera to start capturing images, making it possible to control the camera to capture images of the intruder at a specified time interval.

[0033] In addition to the infrared light mentioned above, a Doppler sensor can also be used as a means for detecting the presence of humans. The Doppler sensor emits ultrasonic waves forward and measures the wavelength shift caused by the Doppler effect in the ultrasonic waves reflected by a moving object. By installing the motion sensor 17, it is possible to prevent burglaries and robberies, and to quickly notify the surrounding area when trouble occurs. It is also possible to distinguish small animals such as dogs and cats from the size of the detected object by the strength of the signal detected by the motion sensor. In preparation for the case where an intruder is detected by the human sensor 17, white LEDs (not shown) can be further arranged concentrically around the photographing lens 12 as a visible light source. In this case, for example, when the infrared LEDs 16 are arranged concentrically around the lens, the LEDs can be arranged on the inner periphery of the concentrically arranged infrared LEDs 16. When the human sensor 15 detects an intruder, visible light such as a white LED can be irradiated on the intruder, making it easier for family members and passersby to visually recognize the presence of the intruder, and irradiating the intruder with a strong white LED beam can also be used to intimidate the intruder.

[0034] (iii) Audio recording microphone When a voice recording microphone that picks up the voices of people in the monitored area is attached inside the surveillance camera unit, the voice information collected by the microphone can be converted into an electrical signal and transmitted to an external communication device together with the electrical information of the image. The voice recording microphone can be attached to the front of the surveillance camera unit, on the outside of the waterproof transparent cover, in the same way as the human presence sensor. The voice recording microphone is a microphone for recording voices, noise, etc., and the voice can be transmitted together with image data to a computer, mobile terminal, etc., and played back if the device has a speaker function. A slit is provided on the side of the housing 13, and a speaker as an alarm means can be installed inside the slit (not shown). When the voice recording microphone or the human sensor 17 detects the presence of an intruder, an alarm sound is emitted from the speaker as an alarm means, and the white LED is further illuminated with light, thereby intimidating and warning the intruder, and it is expected that the intruder will be prevented from entering the house, etc. As described above, in the security equipment of the present invention, the (i) optical sensor and infrared LED, (ii) human presence sensor, (iii) audio recording microphone, etc., which are attached to the surveillance camera unit, can be installed inside the housing 13 of the surveillance camera unit 2, so that the amount of wiring cables around the housing can be reduced. In particular, when the surveillance camera unit is attached to a non-contact power supply device, a power cable outside the housing is not required and the wiring cables outside the surveillance camera unit housing can be eliminated, making installation and maintenance after installation easier.

[0035] (2) Security system (second embodiment) The "security system" of the second embodiment of the present invention includes the security equipment of the first embodiment, (i) An external communication device that receives an electrical signal transmitted from the security equipment via a wireless communication network via the Internet and includes a computer having a function of monitoring and storing the received information (hereinafter, sometimes referred to as the second embodiment (A)); or (ii) an external communication device that receives the electrical signal transmitted from the security equipment via a wireless communication network via the Internet and that is a computer having a function of monitoring and storing the received information; The present invention is characterized in that it includes a mobile terminal capable of communication connection to the Internet via a mobile communication network (hereinafter, sometimes referred to as the second embodiment (B)).

[0036] (2-1) Second embodiment (A) The security system of the second embodiment (A) includes the security equipment of the first embodiment, The security equipment includes an external communication device that receives, via the Internet, an electrical signal transmitted from the security equipment via a wireless communication network, and a computer having the function of monitoring and storing the received information. 3 is an explanatory conceptual diagram showing an example of the second embodiment (A) of the present invention, in which a non-contact power supply device 6 is arranged with an outdoor-side non-contact power receiving component 21 and an indoor-side non-contact power transmitting component 24 fixed in positions facing each other across a building wall 28. A surveillance camera unit 3 installed outdoors at a position away from the non-contact power supply device 6 can receive power from the non-contact power supply device 6 via an electric wire cord 42.

[0037] Image information captured by surveillance camera unit 3 of the security equipment of the first embodiment (hereinafter sometimes simply referred to as security equipment) is converted into a digital signal within the surveillance camera and transmitted to computer 32 via Internet 31, which is installed at a relatively short distance from a wireless communication network such as a wireless LAN. In computer 32, the captured image can be confirmed on a monitor, and the electric signal (digital signal) is stored in a storage device, or it can also be stored in a hard disk drive (HDD) or the like on which image processing software or the like is installed.
